Can I get separate Measles, Mumps, and Rubella vaccines?
Many parents would prefer to split up the MMR vaccine into separate components and give them separated each by a year or more. However, the sole manufacturer of the separated vaccines, Merck, stopped making them separately in 2007. They stated that the demand was too low, and they prefer to use all their manufacturing for the full MMR. And there are no plans to resume making them separately.
